Rapid Prototype Molding Materials
Acrylonitrile Butadiene Styrene
Strong, impact-resistant plastic with excellent toughness and dimensional stability. Widely used for automotive parts, consumer goods, and electronics housings.
Polypropylene
Lightweight, chemical-resistant material with good fatigue strength. Ideal for packaging, automotive components, and medical devices due to its versatility and low cost.
Polycarbonate
High-strength, transparent plastic with excellent impact resistance and clarity. Commonly used in lenses, medical devices, and electronic housings.
Nylon (PA6/PA66)
Strong, wear-resistant engineering plastic with high toughness and fatigue resistance. Perfect for gears, bearings, and automotive under-hood applications.
Polyethylene
Flexible, durable, and chemical-resistant material. Often used in containers, bottles, and packaging films.
Polystyrene
Lightweight, rigid, and cost-effective plastic with good clarity. Used for disposable items, packaging, and lightweight enclosures.
Polyoxymethylene
Low-friction, high-stiffness material excellent for precision components like gears, bearings, and automotive fuel systems.
Polymethyl Methacrylate
Clear, lightweight plastic with glass-like transparency and UV resistance. Widely used in lighting, displays, and windows.
Polybutylene Terephthalate
Strong engineering resin with excellent electrical insulation and chemical resistance. Common in connectors and automotive electrical parts.
Thermoplastic Elastomer
Rubber-like flexibility combined with easy processability. Used for grips, seals, and overmolded components.
Thermoplastic Polyurethane
Elastic, abrasion-resistant, and durable. Ideal for footwear, hoses, and protective cases.
Polyether Ether Ketone
High-performance polymer with extreme heat, chemical, and wear resistance. Used in aerospace, medical implants, and demanding automotive parts.
Polyetherimide
Heat-resistant engineering plastic with high strength and flame retardancy. Used in medical devices, aerospace, and automotive.
Polysulfone
Transparent, tough plastic with excellent heat resistance and dimensional stability. Common in plumbing and medical applications.
Liquid Crystal Polymer
High-flow, heat-resistant resin perfect for thin-wall precision parts in electronics and connectors.
High-Density Polyethylene
Tough, lightweight, and chemical-resistant. Used in bottles, containers, and piping.
Low-Density Polyethylene
Flexible, impact-resistant, and cost-effective. Common in plastic bags, films, and flexible containers.
Ethylene Vinyl Acetate
Soft, rubber-like material with excellent flexibility. Often used in footwear, sports gear, and packaging foams.
Polyvinyl Chloride
Durable, flame-retardant material with excellent chemical resistance. Common in pipes, fittings, and building materials.
Fluoropolymers
